The 1N4150W diode has a cathode (-) and anode (+). In the schematic symbol, the tip of the triangle with the line on top of it is the cathode. The cathode is marked on the body of a diode by a band as shown below.The current can flow from only the anode to the cathode and never from the cathode to the anode - the 1N4150W diode is like a one way electric valve.You can replace the 1N4150W with the 1N4150
